Table 3

As it was noted above, pressure sensor can be used for experiencing pressure signal.For example, when pressure sensor is arranged first When on electrode or second electrode, pressure sensor can detecte the contact pressure of user body parts with first electrode or second electrode Power.When the pressure signal that pressure sensor detects is bigger, illustrate the pressure between user and first electrode and/or second electrode (touch intensity or touching intensity) is bigger (illustrating that user body parts and first electrode and/or second electrode squeeze), when The pressure signal that pressure sensor detects is smaller, illustrates that the pressure between user and first electrode and/or second electrode (touches Intensity or touching intensity) smaller (illustrating that user body parts and first electrode and/or second electrode contact are poor).These situations Under, only have the electric signal of less frequency range available in all electric signals that first electrode and second electrode detect, other frequencies Electric signal is clutter, and the presence of clutter will will affect the generation of ECG.Therefore, processor 614 determines what pressure sensor detected When pressure value is less than P1, it can determine that corresponding frequency domain bandwidth is 0.05-150Hz according to table 3.Processor 614 determines that pressure passes When the pressure value that sensor detects is within the scope of P1~P2, it can determine that corresponding frequency domain bandwidth is 0.5-40Hz according to table 3. Processor 614 determines that the pressure value that pressure sensor detects is greater than P2, can determine that corresponding frequency domain bandwidth is 7- according to table 3 23Hz。

It in some instances, can also include capacitance sensor in sensor subsystem 606, wrist-watch 600 (for example stores Device) in be stored with corresponding relationship between capacitor and frequency domain bandwidth, be a kind of example of the corresponding relationship referring to table 4.

Table 4

As it was noted above, capacitance sensor can be set in first electrode and/or second electrode, work as user body parts When being contacted with first electrode and/or second electrode, capacitance sensor can detecte human body and first electrode and/or second electrode it Between capacitor.When the capacitor that capacitance sensor detects is excessive or too small, illustrate human body and first electrode and/or second electrode It contacts poor；When the capacitor that capacitance sensor detects is moderate, illustrate human body contacted with first electrode and/or second electrode compared with It is good.Therefore, when the value that processor 614 determines that capacitance sensor detects is less than C1, corresponding frequency domain band can be determined according to table 4 Width is 0.5-40Hz.It, can be corresponding according to the determination of table 4 when the value that processor 614 determines that capacitance sensor detects is greater than C2 Frequency domain bandwidth is 7-23Hz.It, can basis when the value that processor 614 determines that capacitance sensor detects is within the scope of C1~C2 Table 4 determines that corresponding frequency domain bandwidth is 0.05-150Hz.

It in some instances, can also include angular-rate sensor in sensor subsystem 606.Wrist-watch 600 (for example store Device) it is stored with the corresponding relationship between angular speed and frequency domain bandwidth, it is a kind of example of the corresponding relationship referring to table 5.

Angular speed	Frequency domain bandwidth
		Less than A1	0.05-150Hz
It is less than or equal to A2 more than or equal to A1	0.5-40Hz
		Greater than A2	7-23Hz

Table 5

In some embodiments, angular-rate sensor can reflect the current motion state of user, therefore, processor 614 When determining that angular-rate sensor detects that value is less than A1, it can determine that corresponding frequency domain bandwidth is 0.05-150Hz according to table 5.Place Reason device 614 determines that the value that angular-rate sensor detects is greater than A2, can determine that corresponding frequency domain bandwidth is 7- according to table 5 23Hz.It, can be according to the determination pair of table 5 when processor 614 determines in the range of the value that detects of angular-rate sensor be in A1-A2 The frequency domain bandwidth answered is 0.5-40Hz.

In some embodiments, the shape that wrist-watch 600 (for example, processor 614 in wrist-watch 600) can be current according to user When state selects suitable frequency bandwidth, the state (such as motion state) of wrist-watch 600 can be only considered, or only consider user's ratio The current state of the user body parts such as contacted with first electrode and second electrode is (for example, skin condition and first electrode And/or contact situation of second electrode etc.)；Alternatively, can also comprehensively consider, for example both considered the motion state of wrist-watch 600, Consider the current skin condition of user, user body parts and first electrode and the contact situation of second electrode etc..For example, The impedance value that wrist-watch 600 is detected by Bio-z sensor detects magnitude of angular velocity by angular-rate sensor, when wrist-watch 600 In the case that (for example, processor 614 in wrist-watch 600) determines that impedance value is greater than Z2, and magnitude of angular velocity is also greater than A2, frequency is determined Rate bandwidth is 7-23Hz.For another example, the impedance value that wrist-watch is detected by Bio-z sensor, is detected by pressure sensor Pressure value, when wrist-watch 600 (for example, processor 614 in wrist-watch 600) determines that impedance value is greater than Z2, and pressure value is also greater than P2 In the case where, determine that frequency bandwidth is 7-23Hz.

In some embodiments, it after processor 614 determines suitable frequency domain bandwidth based on sensor parameters, can be based on The frequency domain bandwidth filters the electric signal that first electrode 616 and second electrode 618 detect.For example, true with processor 614 Frequency domain bandwidth is determined for for 7-23Hz, the frequency for the electric signal that first electrode 616 detects is 65-150Hz, second electrode 618 The frequency of the electric signal detected is 0.05-120Hz.Processor 614 can filter out the electric signal except 7-23Hz.One In a little examples, the electric signal that first electrode 616 detects be can be (v1, t1), and the electric signal that second electrode 618 detects can be with It is (v2, t2)；Wherein, v1 and v2 characterizes voltage, and t1 and t2 characterize the time, and t1, that is, first electrode 616 collects electric signal v1's Time, t2, that is, second electrode 618 collect the time of electric signal v2.Therefore, processor 614 obtains voltage and changes with time song Line, and then available frequency domain versus time curve, i.e. ECG waveform.

In the above embodiments, the physical feeling with first electrode 616 and second electrode 618 of user contacts, the first electricity Pole 616 detects the first electric signal, and second electrode 618 detects the second electric signal, the state current according to user of processor 614 Suitable frequency bandwidth is selected, then according to the frequency bandwidth selected to the first signal and the second signal processing.At other In embodiment, original frequency bandwidth is stored in wrist-watch 600, for example original frequency bandwidth can be the frequency bandwidth of default, or When person is 600 last time of wrist-watch detection ECG, frequency bandwidth used etc..It is detected in first electrode 616 and second electrode 618 To after electric signal, processor 614 can judge whether to need to adjust original frequency bandwidth according to the current state of user；If so, Then processor 614 adjusts original frequency bandwidth, obtains ECG signal (for example, using adjusted using frequency domain bandwidth adjusted Frequency bandwidth filters the first electric signal and the second electric signal, then obtains ECG using filtered electric signal)；If it is not, then locating It manages device 614 and obtains ECG signal using original frequency bandwidth.

For example, in the case where including angular-rate sensor in sensor subsystem 606, processor 614 judges angle speed When the value that degree sensor detects is larger, the range of original frequency bandwidth can be reduced.Processor 614 judges angular-rate sensor When the value detected is smaller, the range of original frequency bandwidth can be increased.It should be noted that reduce increase original frequency band Wide amplitude can be default setting or user is customized, and the embodiment of the present application is not construed as limiting.

For another example, in the case where including pressure sensor in sensor subsystem 606, processor 614 judges pressure sensing When the pressure value that device detects is larger, the range of original frequency bandwidth can be reduced.Processor 614 judges that pressure sensor detects When the pressure value arrived is smaller, the range of original frequency bandwidth can be increased.

In further embodiments, after wrist-watch 600 starts ECG automatic detection function, user body parts and wrist-watch 600 On first electrode and second electrode contact.First electrode detects the first electric signal, and second electrode detects the second electric signal. The electric signal filtration treatment that processor 614 can acquire first electrode and second electrode using initial frequency-domain bandwidth, then base Initial ECG signal is generated in filtered electric signal.The sensing that processor 614 can be detected according to sensor subsystem 606 Device data judge whether the initial ECG is accurate, if inaccurate, adjust initial frequency-domain bandwidth, are then based on frequency adjusted Bandwidth acquires new ECG, if new ECG inaccuracy, can adjust frequency domain bandwidth, until the ECG of acquisition is accurate again.With Under introduce processor 614 according to sensing data judge ECG whether accurately possible implementation.

For example, Fig. 7 shows the schematic diagram for the initial ECG waveform that processor 614 is obtained using original frequency bandwidth. Processor 614 determines the wave crest or trough for including in unit time (such as 5 seconds, 10 seconds, 20 seconds etc.) in the initial ECG waveform Number is denoted as N.In the case where including PPG sensor in sensor subsystem 606, processor 164 can pass through PPG sensor Human heart rate's value is obtained, M is denoted as.Processor 614 determines whether the difference between the M and N is greater than threshold value, if so, Determine ECG inaccuracy, if not, it is determined that ECG is accurate.It is adjustable initial when processor 164 determines ECG inaccuracy Frequency domain bandwidth acquires new ECG again, until the heart rate value that processor 163 determines that PPG sensor detects is obtained with by ECG To unit time in wave crest or trough number between difference be less than or equal to threshold value until.

In further embodiments, user carries out all kinds of behavioral activities (for example, running, being quiet during wearing wrist-watch 600 It lies).After the physical feeling of user is contacted with first electrode and second electrode, first electrode detects the first electric signal, second Electrode detection is to the second electric signal.Wrist-watch 600 can judge whether to respond the first electric signal and the according to the current state of user Two electric signals (for example, ECG is obtained according to the first electric signal and the second electric signal).Wherein, the current state of user may include The current movement velocity of user, skin condition etc..In some instances, processor 614 can pass through sensor subsystem 606 The sensing data detected judges whether to respond the first electric signal and the second electric signal (for example, according to the first electric signal and the Two electric signals obtain ECG).

It for example, may include Bio-z sensor in sensor subsystem 606.Assuming that processor determines that Bio-z is sensed The smaller such as less than threshold value of the human body impedance value that device detects 1 (it is illustrate water stain more on human skin, for example perspire, wet water Deng), the first electric signal and the second electric signal can be not responding to.In some embodiments, processor is not responding to the first signal and In the case where binary signal, prompt information can be exported, for example the prompt information can be " body surface is water stain more, can not detect " etc.. In some embodiments, the voice letter that prompt information can be played with the information such as text, image on display or loudspeaker Breath etc..Assuming that processor determines that the human body impedance value that Bio-z sensor detects is suitable (for example, in threshold value 1 to threshold value 2 In range), the first electric signal and the second electric signal can be responded, for example, being given birth to according to the first electric signal and the second electric signal Manage parameter, such as ECG signal.

It for another example, may include motion sensor, such as angular-rate sensor in sensor subsystem 606.In some realities It applies in example, wrist-watch 600 can establish coordinate system (for example, two-dimensional coordinate system or three-dimensional system of coordinate), for example, wrist-watch 600 can be with Some point (such as central point or the point on point or wrist-watch frame on edge etc. of display screen) is that origin establishes coordinate System, angular-rate sensor can detecte one in the gravity direction and the coordinate system of wrist-watch 600 in x-axis, y-axis and z-axis or The pace of change of angle between multiple axis.Fig. 8 shows the signal of the wrist-watch building coordinate system of one embodiment of the application offer Figure.As shown in figure 8, user wears wrist-watch (for example, wrist-watch 600).Wrist-watch 600 a little constructs three-dimensional sit on display platen edge Mark system, angular-rate sensor detect the variation of the angle between one or more axis in gravity direction and x-axis, y-axis and z-axis Speed.When processor 614 determines that angular-rate sensor detects the variation of the angle between gravity direction and one or more axis When speed is not 0, determine that wrist-watch 600 is kept in motion.When processor 614 determines the gravity side that angular-rate sensor detects When the speed change speed of angle between method and any one axis is 0, determine that wrist-watch 600 remains static.

In some embodiments, processor 614 determines that wrist-watch 600 is in static by the value that angular-rate sensor detects When state, the first electric signal and the second electric signal can be responded (for example, obtaining physiology according to the first electric signal and the second electric signal Parameter).In further embodiments, processor 614 determines that wrist-watch 600 is in movement by the value that angular-rate sensor detects When state, the first electric signal and the second electric signal can be not responding to.In some embodiments, wrist-watch 600 is not responding to the first telecommunications Number and when the second electric signal, prompt information can be exported, for example prompt information can be and " can not detect, please keep quiet when movement Only " etc..

In further embodiments, when the value that processor 614 determines that angular-rate sensor detects is greater than 0 less than threshold value, The first electric signal and the second electric signal can be responded, for example physiological parameter is obtained according to the first electric signal and the second electric signal, than Such as the ECG signal of user.When the value that processor 614 determines that angular-rate sensor detects is greater than the threshold value, it can be not responding to First electric signal and the second electric signal.That is, also available ECG believes when wrist-watch 600 detects that motion amplitude is smaller Number, when wrist-watch 600 detects that motion amplitude is larger, prompt information can be exported, to prompt user movement amplitude too big.

It for another example, may include pressure sensor in sensor subsystem 606.When processor 614 judges pressure sensor When the pressure value detected is less than threshold value, the first electric signal and the second electric signal can be responded, for example, according to the first electric signal and Second electric signal generates physiological parameter, such as ECG.When processor 614 judges that the pressure value that pressure sensor detects is greater than threshold When value, the first electric signal and the second electric signal can be not responding to.In some embodiments, wrist-watch 600 can export prompt information, The prompt information such as can be " pressing dynamics are excessive, please touch " etc..

In the above-described embodiment, after the physical feeling of user and first electrode and second electrode contact, wrist-watch 600 Suitable frequency bandwidth is selected to obtain ECG.That is, when wrist-watch 600 determines the physical feeling and first electrode and the of user After the contact of two electrodes, the processing such as selection, adjustment or determination of bandwidth frequency is just carried out.In the application other embodiments, hand After table 600 starts ECG automatic detection function, sensor subsystem 606 can be in enabled state always.Sensor subsystem 606 can constantly, detection sensor data in real time.Processor 614 constantly, can be selected in real time by sensing data Select suitable frequency bandwidth.When wrist-watch 600 determines that the physical feeling of user contacts (first electrode with first electrode and second electrode Detect the first electric signal, second electrode detects the second electric signal) when, processor 614 uses the frequency band having been selected out The electric signal filtration treatment that width acquires first electrode and second electrode, is then based on filtered electric signal and obtains ECG signal. In this embodiment, wrist-watch 600 in real time, is constantly selected by the sensing data that sensor subsystem detects suitable Frequency bandwidth, when user body parts and first electrode and second electrode contact, wrist-watch 600 has been selected out with regard to using Frequency bandwidth is handled, and raising efficiency is facilitated.

The process for selecting suitable frequency bandwidth according to sensing data about wrist-watch 600, is being already mentioned above, herein It does not repeat to repeat.

In some embodiments, the mode of machine learning can be used in processor 614, according to the ECG signal detected, comments Estimate the health status of user.Alternatively, processor 614 module or mobile communication module can send ECG by wireless communication Server to network side or the electronic equipment such as mobile phone with 100 bluetooth connection of wearable device, by server or mobile phone according to ECG assesses the health status of user.For assessing the health status of user in such a way that wearable device 100 uses machine learning. The health status of the model evaluation user of storage can be used in wearable device 100.Wherein model can be including inputting parameter, mould Functional relation between shape parameter and output parameter.It illustratively, can be defeated by the ECG after wearable device 100 obtains ECG Enter into model input parameter of the i.e. ECG as model, moving model is exported as a result, the output result i.e. user health shape State information (such as text information shown in Fig. 9).In order to improve the accuracy of model output result, wearable device 100 can be instructed Practice model.Wherein model training can be, to wearable device 100 input corresponding with the ECG health status information of ECG (such as Inputted by input equipment or the other electronic equipments being connect with wearable device 100 such as network side server), wearable device ECG is input to model by 100, and moving model is exported as a result, the output result i.e. health status information. Wearable device 100 can compare output result health status information corresponding with received ECG and illustrate this if differing greatly Model accuracy is poor, adjustable model parameter, again moving model, until adjusting model parameter, the model it is defeated Difference out between result health status information corresponding with the received ECG of wearable device 100 is smaller.The process is only that introduction will One ECG carrys out training pattern as mode input parameter, in practical applications, can be using several ECG as the input of model Parameter (for example, inputting several ECG and the corresponding health status information of each ECG to wearable device 100), obtains several A output illustrates this as a result, if each output result or most end of output are smaller with the health status difference that receives Model accuracy is higher.After model training is completed, the model is can be used in wearable device 100.For example, wearable device 100 After obtaining ECG according to the first electric signal and the second electric signal, by the ECG input model, it is i.e. strong to obtain output result for moving model Health status information.
